FN’s Black Box for Guns

This nifty gadget, made by FN Herstal, can be installed anywhere on a gun where it can be squeezed in, such as the pistol grip in the above photo. It can record shot count, firing sequences and more.

    While many people’s instinct may be that this is a bad thing, I can see this really helping with maintenance scheduling for the military/police and I can see this actually helping the user in litigation rather than hurting them. Naturally this should not be a required item, but rather elective.

    My WAG is that it works by measuring acoustic signatures and classifying them with a bank of matched filters, or possibly it could contain a MEMs IMU to measure inertial modes. This would allow differentiation between a gun being fired nearby and the user’s weapon. The rest of it is most likely just standard digital counting to infer timing.

    A really basic version of something like this would be a good electrical engineering junior/senior design project.


  • lol

    u want some pics of that ??? like with the gun and all ?

    • lol, if you have some, please sent them through. My email is on the contact page (link at the top).

    This is going to be an useful asset for SWAT Teams so they can count who shot what and when.

    On the other hand, civilian applications are rather limited.

    Finally a gadget from FN thats useful. Is the grip modular in size?

  • lol

    well i will take them tomorow or on friday … i got to go to FN … 😀
    I have some other Fn stuff to show u

  • SOCOM has had a weapon shot counter (WSC) requirement for quite awhile. The collected data will allow them to preemptively replace parts before they wear out and/or break.

    • Daniel, do you know whose system they used?

  • As far as I know, there has not been a contract award yet.

    This actually could be very useful. As previously stated, it could help with preventive maintenance, but could also be tied into magazine ammunition count. If the sensor suite also contains accelerometers, it may be able to measure impulse, with data being used to tailor ammunition for consistency.

    As long as the data is both local and eraseable, this may not be a terrible thing, as long as use and installation is completely voluntary.

    Technology is increasingly becoming an integral part of firearms and/or their support systems. as the miniaturization of electronics continues you’ll see more and more interactive and smart devices become part of the firearm industry.

    The Blackbox (and similar systems) is interesting, especially when combines with other peripherals like the Moving Red Dot.

    It is future fact and modern warfare plat formed as coast sight, or force kill technology,
    The actual design and training is best kept secret, But most advanced teams, and other actual warfighter programs know that it feels like a modern game you mite play, yet most soundly agree that the truth about the AI industry and other machine paths are fare from shared. The Idea for digital round control and display is a very good thing, Even more so when you think beyond just tactical reloading and trace fire positioning, but into the field of atmosphere control and anti biologicals, programmable rounds and other tricks to leave the theater kill actions shorter. knowing this and actually training into it is different, what flows is what works. An AI set up is not talked about very much, yet command and control agree on the hat of it giving combat actions an edge. The best thing about a working display is reengineering the actions in working battle form after training, Computer modules and 3d camera usage, like more then one view point are handy, But you need a comprehensive understanding of ware fighting structure, and that means looking past blood and ego history. Machining data and moving soldiers dynamically force scope of mission planning and training and dealing with advanced enemy groups means not leaving the study of technology behind or the actual history books covered up. The M4 is a strong action design and is very programmable with add carbon fiber and return moisture temperature control, next phase powders and other more ideas based at its building, set a good path for smoother threat controls, The idea of saying I can hear and I also just simply know how many rounds I have is not a bad idea, yet when you learn more about the relationship, positioning, fire field acceleration, quickening or slowing the movement of the enemy, taking control and keeping has a ton to do with how your leaders know how you see and feel through the combat, as you move the learn and teach back progression, That aid in the flow and placement of logistical combat data, If I can copy your fire and eye beat, or optic fast path, team or unit, I can shield your position with just a few moves of pressure, We need zero loss war skill, some hot heads say that is a pipe dream, Yet most good team trainers say, yes, with the right data package, shielding and force legal and control scope, logistics and a few tricks like team buddy cross training, over paths, AIs body ups, exoskeletons is also in that idea framing, magnetics electric and plasma rnd as well,. All picture aids and smarter weapons for smarter warriors. Moving and keeping the image of a battle plan, Any officer will tell you, The less you tell your troops the more your trying to steal from them. Awareness is a unity aspect, sound suppression cross coms head geared with a low exposure anti round composite carbon fiber hybrid is a little more high speed, yet also digital displays show us how to control adrenalin situations and aid in quick first kill conditionings and mental next motion actions, or tactical pass making. Using cross thermal awareness and structuring the data locally team by team adds in stealth programing options, and if your team mate can see how many rounds you have left in a fire fight, That could make the difference between having that shield of action or not, Less gaps better naps.,,Stake for the meat lover and water for the host of ghosts.
